I took a quick look and you seem to be still using BB 1.7.5. Can you try updating that to the latest version of 1.7.6; we’ve made specific changes involving fontawesome.
Sorry to hear about that! Took another close look and it appears that the cause of the issue is this CSS code below that you’ve added in Layout Settings > CSS.
We’re using Fontawesome for our icons so your code overwrote Fontawesome as the font-family because of the wildcard. Glad to hear it’s all sorted out now and thanks for taking the time to let us know. We appreciate it!
